    Q:
    How to Repair the Shift Knob on a GMC Acadia? Posted by Customer
    A:
    The first step to replace the Shift Knob requires application of the parking brake followed by removal of the floor console left extension panel. Use an electric connector plier to disconnect the transmission tap up/tap down switch electrical connector then turn the key to the run position while keeping the vehicle engine off. A flat bladed tool must be inserted behind the trim ring to separate it from the Shift Knob allowing an approximate 13.0 mm (0.5 in) drop of the Shift Knob to reveal the retaining screw. Begin unscrewing the Shift Knob screw by 4-5 turns keeping the electrical harness of the transmission tap up/tap down switch past the shift control indicator while you take out the Shift Knob. After guiding the Shift Knob to its position on the shift control lever you need to pass both the electrical harness and connector through the indicator again. Attach the knob screw which had been taken off and secure it at 4 n.m (35 lb in). Clicks will signal that the Shift Knob trim ring has properly secured to the knob after being lifted over it. The transmission tap up/tap down switch electrical connector can be attached when the key is in off position and the shift control lever is set to park position. The operator should inspect shift control functioning across all gear ranges then put back the floor console left extension panel before letting go of the parking brake.

    Q:
    How to Change the Shift Knob on a GMC Acadia? Posted by Customer
    A:
    The first step to changing the acadia's Shift Knob involves applying the parking brake followed by removal of the floor console left extension panel. Disconnect the transmission tap up/tap down switch electrical connector then rotate the key into run position without engine activation. A thin flat-bladed tool should be gently inserted between trim ring and Shift Knob layers to ease the trim ring off the Shift Knob because these pieces will separate by approximately 13.0 mm (0.5 in). Only after screwing out the Shift Knob screw can you safely guide the transmission tap up/tap down switch electrical harness and connector above the shift control indicator when removing the Shift Knob from the shift control lever. To assemble the Shift Knob users must apply p/n 88861426 lubricant to the shift control lever tip followed by proper electrical harness guidance when putting the Shift Knob in place onto the shift control lever. Secure the knob screw by tightening it to 4 n.m (35 lb in). The Shift Knob trim ring needs lifting until you hear a clicking sound to show proper mounting to the Shift Knob. After this set the shift control lever to park position and turn off the key. Check the transmission tap up/tap down switch electricity and verify shift control operation through all ranges before installing the floor console left extension panel along with brake release.
